Classification of protective film:

There are four problems that should be paid attention to when pasting protective film on automobile: explosion-proof function, ultraviolet isolation rate, light transmittance and heat insulation rate.

Car film is to stick a layer of thin-film objects on the front and rear windshield and skylight of the vehicle. The primary effect is to block the attack of ultraviolet rays, some heat and injuries caused by the sudden bursting of the glass, so as to achieve the intention of maintaining personal privacy. Shenzhen Dongmei protective film company introduces these four problems of car film.

Explosion proof function

This is also another important function of touching safety. The excellent explosion-proof film has strong resistance. After the glass is broken, the film can be adhered firmly without splashing and hurting people, and its impact resistance is very strong. The defective explosion-proof membrane feels very soft, lacks satisfactory patience, is not resistant to ultraviolet light, and is easy to aging and brittle.

UV isolation rate

For high-quality membrane, the target is usually no less than 98%, and the high can reach 100%. The high UV isolation rate can effectively prevent the people in the car from being illuminated by excessive UV rays and burning the skin, and also maintain the sound in the car from being damaged by the sun. Many of the defective membranes do not have this goal, or are far below the 98% specification. This is also the primary basis for product warranty period.

Light transmittance

This is the most important function related to driving safety in the car film. It is recommended that users try not to select the film with too low light transmittance. The window film, especially the film on both sides of the front row, and the substrate selected for the front gear film should be clear. Even if the film with darker color, the scene should be transparent, not dim and deformed.

The transmittance shall be more suitable than 85%. At this moment, the side window membrane does not need to dig holes and does not affect the field of vision. When driving at night, it can shine the headlights coming from behind on the inverted rear mirror, which weakens the intense glare reflection and makes both eyes very comfortable. In addition, it can ensure excellent vision when driving, reversing and turning around on rainy nights.

Tser 

The explosion-proof film of a good quality car can reflect infrared rays, so the temperature in the car is much lower, which will reduce the air-conditioning load and save fuel. If the car is the first to judge, the method is very simple. As long as you block the sun with coated glass and feel its heat insulation effect with your face or hands. The use of car film can reduce the damage caused by ultraviolet radiation of objects and personnel in the car, save fuel consumption to a certain extent, and reduce the aging of car interior.
